The antilegionella cycle:
• Is enabled in the time bands set by scheduler
• is always the priority on the ambient
thermoregulation
• SetPointaccumulo uses only the electric
resistances
• SetPointaccumulo can use the heat pump instead
of the resistances.
STORAGE phase:
• It is disabled in the time bands set by the scheduler
• During this phase, the heat pump produces DHW if
the storage temperature drops down the DHW band
set point: medium storage temperature
MAINTENANCE phase:
• always active but not during the storage phase
• this phase, unlike the previous, agrees that the
medium temperature drops furtherly down before the
heat pump is activated : medium storage
temperature
